• Footnotes:
• 1. Most Wiseco pistons have offset pins. Pins must be offset same as o.e. for quietest operation (pin offset will be opposite of direction of engine rotation).
• 2. Due to a compression height that may protrude above the deck, it is recommended that a .040" thick head gasket is used.
